100 Watt Solar Panel Price – Its Specifications, and Features
Do you ever worry about going on an outdoor trip and your phone running out of battery? A 100 Watt solar panel can charge it for you! You can take it for hiking, trekking, and adventurous biking trips. The 100 watt solar panel price offers excellent value for money and is highly affordable.
The solar system consists of solar panels and other components like UPS, battery, wires, etc. The 100 watt solar panel system price depends on the cost of the components of the solar system.
If you want to run DC devices directly, we recommend you do it via an output controll circuit. While it is possible to run devices such as a DC fan or bulb directly from the solar panel’s electricity, the voltage and current fluctuation can damage the devices. A controller will provide much-needed stability to input received by the devices.
If you want to run AC devices with solar electricity, you will also need a UPS for converting the DC into AC and protecting your devices from any current fluctuations.

While a 100 watt solar panel is perfect for running small devices such as fans and bulbs, you can install a larger rooftop solar system to run devices such as fridges and ACs. For example, if you monthly consume less than 400 units of electricity, you can install a 3 kW solar system. You can learn about the benefits of a 3 kW solar system by reading our blog on 3 kilowatt solar panel price.
Types of 100 Watt Solar Panels
There are 2 main types of 100 Watt Solar panels that you can buy:
- Mono-PERC 100 Watt Solar Panel
They are the most efficient solar panels in the market. A single silicon crystal is used to manufacture the cells for these panels. You can identify them by their black colour.
- Polycrystalline 100 Watt Solar Panel
The cells in a polycrystalline solar panel are made from multiple silicon crystals. You can identify polycrystalline panels by their blue colour.
Here are the efficiencies of both these panels at a glance:
Type of Panel | Efficiency |
Polycrystalline | 13-17% |
Mono-PERC | 20-21% |

Do You Need a Battery with a 100 Watt Solar Panel?
Yes, a battery is compulsory for running devices with a 100 W solar panel.
You will need a charge controller between the solar panel and the battery. The charge controllers available in India usually don’t work without a battery. And even if you do find a charge controller which will function without a battery, you could end up damaging the charge controller and the device if you don’t use a battery.
100 Watt Solar System Components
Here’s a brief idea of the function of the components of a 100 W solar system:
- Solar Panel
The solar panel generates electricity. For maximum efficiency, the sunlight must fall perpendicularly on the solar panels.
- Battery
A battery is necessary for storing the electricity generated by the solar panel. If you are on a low budget, you can consider buying a 75 Ah battery at Rs. 7000 to Rs. 8000. If you can afford to spend a bit more, you can instead buy a 100 Ah battery at Rs. 8,000 to Rs. 10,000.
- Charge Controllers
A charge controller regulates the current which goes into a battery. It protects the battery from overcharging and overvoltage.
- UPS
The UPS converts the DC power into AC power which can be used for household purposes. It maintains the stability of the current and the voltage which is entering the devices. This ensures that the devices don’t get damaged by any fluctuations in the electricity.
- Wires
You can choose between wires of 1.5 sq. mm and 2.5 sq. mm. If you plan to increase the number of solar panels in the future, you must buy a 2.5 sq. mm wire. It will help you accommodate the increased capacity.

Power Generation from a 100 Watt Solar Panel
To calculate power generation, you can multiply the wattage of the panel by the duration for which it receives sunlight. If the panel receives peak sunlight for 5 hours, the power production will be 100 W x 5 hours = 500 Wh.
The duration for peak sunlight in India is between 4 to 5 hours. Thus, a 100 W solar panel can daily generate 400 Wh to 500 Wh of electricity. Monthly, it will generate 12 kWh to 15 kWh of electricity.
But what if your power needs are much greater? If you consume around 600 units of electricity monthly, you can reduce your electricity bills to zero by installing a 5 kW solar system. To find out the cost of installing a 5 kW solar system, you can read our blog on 5 kW solar panel price.
How Long a 100 Watt Solar Panel Can Run a Device?
You can calculate the duration for which power from a 100 Watt solar panel can run a device by using the following formula:
Duration for which power from a 100 Watt panel can run a device = Power Generated by Panel/Power Rating of the Device
For example, if the solar panel has generated 500 Wh of power, and your device has a power rating of 30 W, then you can run the device for 500 Wh/30 W = 16.67 hours.
Here’s the duration for which different devices can run from the power generated by a 100 Watt solar panel in a day:
Device | Wattage | Duration* |
Light | 20 W | All Day |
Table Fan | 50 W | 10 hours |
Ceiling Fan | 75 W | Over 6 hours |
Laptop/Tablets | 80 W | Over 6 hours |
How to Maintain a 100 Watt Solar Panel?
Here are some steps you can follow to maintain your 100 W solar panel:
- Keep your solar panel clean, don’t let any dust accumulate on its surface.
- Ensure that animals such as rats, insects, ants, etc., don’t get anywhere close to your solar panel.
- Inspect your panel for any indication of damage.
- Check all the connections. Wires, cables, and connectors must be properly connected.
Factors Affecting 100 Watt Solar Panel Output
The following factors the output of a 100 Watt solar panel:
- Angle of Incidence of Sunlight
For maximum production of electricity, sunlight must fall perpendicularly on the panels. The more oblique the angle of incidence is, the lesser the electricity generation will be.
- Shadow
A shadow can reduce the power output of your panel to zero. Ensure that no shadow falls on your panel.
- Pollution
Dust and objects such as leaves can cover your panel and reduce its efficiency. So ensure the cleanliness of your panels.
- Type of Panel
The technology of a panel decides its efficiency. A mono-PERC panel is more efficient than a polycrystalline panel, so the electricity generated by the former is greater as well.
